I'm after a couple more pairs of descender rings but I know if I go on Paul's site it'll end up costing me fortune again

So a quick google led me to these over this side of the pond ....

They're rated to the same as the ones I've already got and the colours seem to match those I got before from Paul.

They're made by slingrings.com apparently if anyone can vouch for them ??
